Data collection
Enrollment in DD2 includes a questionnaire and the collection of urine and blood samples. The questionnaire includes a section with a few questions for the patient to fill out (at registration for enrollment) and another to be filled out by the enroller (at enrollment). All individuals older than 18 years of age diagnosed with diabetes within the last 2 years are eligible for inclusion in DD2 (previously, a longer diabetes duration was allowed).
The individual can either sign up online (and then be contacted) or be approached by the practice personnel (e.g., during a regular diabetes check-up). The individual will receive an e-mail with a link to WebPatient, where a few questions should be filled out before the questionnaire will be sent to the practice. Hereafter, a DD2 examination will take place, where additional questions will be answered (e.g., a clinically assessed diabetes debut date) along with a physical examination (e.g., to measure weight, hip and waist circumference, and resting heart rate). The examination also involves a urine sample (morning urine) and a blood sample (fasting).
Enrollment can either take place in the general practice (GP) or in the outpatient clinic. Registration is also possible for individuals without internet access. For further information about the enrollment, please see the DD2 website (Danish): Patient information and Instructions and questionnaires.
